All on 4 Implant Technique

all on 4 melbourne


All-on-4 implants are a series of fabricated teeth that are permanently attached to dental implants that have been surgically implanted into your jaw. They have the same appearance, feel, and work as natural teeth.


  • Are permanent teeth that can be washed and cleaned in the same way that natural teeth are.
  • Do not have to be taken out
  • Adhesives are not needed.
  • Since they don’t rub against your gums, they’re really comfortable.
  • Enable you to get a better sense of what you’re eating.
  • Allow you to bite harder, allowing you to enjoy all of your favorite foods once more.
  • Bone resorption should be avoided at all costs.
  • Restore the presence of your face

All on 4 Implant Concept

The “all-on-4” implant concept was created to optimize the use of usable remnant bone in atrophic jaws, allowing immediate function while avoiding regenerative procedures that increase treatment costs, patient morbidity, and complications. To assist a provisional, set, and immediately loaded prosthesis, the protocol places four implants in the anterior part of complete edentulous jaws. The two most anterior implants are positioned axially, whereas the two posterior implants are positioned distally and angled to reduce cantilever length and enable for the use of prostheses with up to 12 teeth, thus improving masticatory performance. As a prelude to the subsequent tendencies, the initial Brnemark surgical-prosthetic procedure proposed the placement of 4 implant fixtures for the reconstruction of a resorbed mandible and 6 implant fixtures on mandibles that showed minimal to moderate resorption. Immediate loading procedures for edentulous jaws are gaining popularity among clinicians and patients alike. The predictability of implant therapy, regardless of the loading regimen used, is demonstrated by high survival rates and a low incidence of complications. Today’s challenge is to build simple and cost-effective protocols rather than proving functionality.

Several research and clinical reports have identified the all-on-4 definition, which was summarized in a previous study. However, the key descriptions at the time were limited to survival rates, implant failures, and technological complications, with little focus on biological complications like peri-implant diseases, which are now known to be very common. There are discrepancies in the literature, mostly in terms of clinical indications, since no consensus on surgical procedures and prosthetic protocols has been reached. The aim of this systematic review was to summarize and update the all-on-4 treatment model, as well as surgical and prosthetic topics, using clinical trials with at least a 36-month follow-up duration.

All on 4 Implant Technique

The All-on-4 technique is built to use only four implants that are ready to work right away. Since all-on-4 implants do not need bone grafting, they are an excellent option for patients with low bone density or volume.

You will be safely numbed until the operation starts so that you do not experience any pain or discomfort. After that, four dental implants are positioned where the bone volume is the best. The new or current denture is used as the basis for a temporary collection of teeth that will be added the next day after the implants have been inserted.

The temporary teeth are removed and the new, permanent collection of teeth is rendered and anchored into place permanently until the bone has completely integrated with the implant (3-4 months).

All on 4 Treatment Planning

The All-on-4 treatment planning is a graftless, cost-effective approach that offers patients a fixed full-arch prosthesis the same day they have their surgery.

Among the characteristics are:

Only four implants are required for full-arch rehabilitation. Two anterior implants that are straight and two posterior implants that are tilted up to 45 degrees Immediate Function (fixed provisional bridge) Bone grafting is prevented in patients who meet the requirements for immediate implant loading by tilting the posterior implants and using accessible bone. On the day of surgery, a fixed full-arch prosthesis improves patient satisfaction in terms of work, esthetics, meaning, voice, and self-esteem.

Treatment periods are shorter.

The posterior implants are tilted, which eliminates the need for time-consuming bone grafting procedures and allows for immediate loading. Cost-cutting In contrast to traditional implant treatment modalities for the edentulous and soon-to-be edentulous jaw, this concept is the least expensive.
